Partner Platforms
Timestamps are great, but they are even better when combined with digital signatures. The partners below support our timestamps in their digital signature systems.
Adobe Acrobat 7 and later include digital timestamp functionality, which is provided by an Adobe-supplied signature framework. DigiStamp provides the Internet-based timestamp server to create the third-party timestamp. Additional information is available here.
E-Lock ProSigner and DeskSeal Web support using DigiStamp's Internet-based timestamp servers. ProSigner supports the third-party application like MS Word, Excel, Adobe Acrobat and allows user to sign documents within these applications. See elock.com
Emeraz offers services to musicians including copyright protection provided by DigiStamp's e-TimeStamp. We recommend this partner for musicians seeking a more complete support service at a very affordable price. See Emeraz.com.
Timestamping Alternatives
These options require programming
An example of using Bouncy Castle Java tools comes with our Java toolkit. Our example uses DigiStamp code only for the communication step to provide automatic failover between our two sites. Additional information is available here.
OpenSSL supports RFC3161 timestamps a can be used to create a time stamp request and verifying the DigiStamp timestamp, details available here.
This testing was done by one of our customers. The The S/MIME Freeware Library (SFL) was available here, we are unsure of its current status
This testing was done by one of our customers. In the Oracle documentation,
see the class HttpTSPRequest for support of RFC 3161 timestamps.
We have not been able to resolve the problem of using OpenTSA with HTTP authentication. Our timestamp servers authenticate the user with their user ID and password. An alternative is to use the DigiStamp Gateway Proxy because it does not require client authentication.
We are not able to support Microsoft Office timestamps because: Office does not provide the function to "authenticate" the client to the TSA Server; for example, there is no place to enter the account number and password (as of 2011-01)
We do not support Authenticode timestamps; they are a unique format used in Microsoft code signing. The timestamps from DigiStamp are in a different PKI / IETF format that was a part of digital signature standards.
